BIO-OPTICS WORLD, March 2008 ARTICLESBio-Optics World is a bi-monthly magazine that provides news, analysis and explanation of applications involving lasers, optics and imaging systems in the life sciences. The magazine is dedicated to giving readers a firsthand look at cutting-edge research related to the design, development and utilization of optical technologies in the study, diagnosis and treatment of disease and disease processes. Bio-Optics World is available by FREE subscription as an electronic (PDF) download. Subscribers must log in to download electronic issues. Table of ContentsFeaturesFeature FocusDiscussions about how to motivate the medical community to embrace new technologies often focus on form and function—user-friendliness, compactness, ergonomics, speed, cost, and so on.
MicroscopyRecent developments in Ti:sapphire lasers are extending CARS and multiphoton microscopy, and enabling new nonlinear imaging methods.
Fluorescence ImagingFluorescence lifetime is the signature of a fluorescent material, used primarily for protein-protein interaction experiments like signal transduction studies, but also for pH measurements inside cells and other ion concentrations.
Diagnostic ImagingThe scientific-imaging, broadcast, factory-automation, and industrial-video markets are discovering the many advantages of using 3CCD (three-chip) technology in diagnostic, video-imaging, and process-control equipment.
DepartmentsBioOptics BreakthroughsIn the first application of high-throughput DNA sequencing technology to investigate an infectious disease outbreak, scientists from Columbia University Mailman School of Public Health, the Victorian Infectious Diseases Reference Laboratory (Melbourne, Australia), the Centers for Disease Control, and 454 Life Sciences link the discovery of a new arenavirus to the deaths of three transplant recipients who received organs from a single donor in Victoria, Australia, in April 2007.
News & ViewsSometimes the simplest solutions can achieve surprisingly significant results. Using an inverted Olympus culture microscope, researchers from the University of Michigan (UM; Ann Arbor) were able to track down the cells responsible for neurofibromatosis type 1 (NF1), an incurable condition of the peripheral nervous system that afflicts one in 3500 Americans.
Over the last few years the SPIE Biomedical Optics (BiOS) portion of Photonics West has grown dramatically, reflecting the continued growth of the industry.
Optical supercontinuum lasers produce light across a broad spectrum in high-power, ultrafast pulses.
Researchers at Northeastern University (Boston, MA) have developed a method based on vibrational microspectroscopy that automatically identifies cancer in human cells without the need for sample staining.
Canadian researchers have developed a technique that relies on nonlinear optical effects to detect the existence and extent of the malaria parasite in human blood.
Last April, when fiber-laser developer IMRA America (Ann Arbor, MI) signed a supplier agreement with Carl Zeiss Meditec (Jena, Germany) for Zeiss’ Visumax laser keratome system, the event marked a significant turning point for IMRA.
Scientists, academicians, and representatives of government and industry spent several days discussing the future of biomedical optics at the first International Congress on Biophotonics (ICOB; Feb. 3–7; Sacramento, CA), sponsored by the NSF Center for Biophotonics Science & Technology (CBST; Davis, CA).
Stimulated emission-depletion microscopy represents one of the most straightforward among techniques to image at a resolution beyond the diffraction limit.
Three years ago, when Reliant Technologies (Mountain View, CA) introduced the first fractional laser skin rejuvenation system, the initial reaction by many was “do we really need another laser in this market?” But what Reliant brought to the market at that time was, in fact, a revolutionary technique that has garnered the company healthy sales and spurred a number of competitors to follow suit.
PioneersGrowing up in Maryland as the son of immigrants from Pakistan and India, Arjun Yodh was more interested in professional sports and music than science.
End Result“At your fingertips” takes on a whole new meaning with Hitachi Information and Control Solutions’ (Tokyo, Japan) finger-vein scanning authentication device.
ColumnsEditorialLast December at the Neuroscience 2007 meeting in San Diego, CA, former U.S. Speaker of the House Newt Gingrich stood before thousands of physicians, researchers, and students and implored them to become citizens “for at least 15 minutes every six months” if they want the U.S. Congress to continue funding scientific research and education.
In the LoopWith the upcoming presidential election, the war in Iraq, and economic issues all vying for valuable floor time in the U.S. House and Senate, other critical issues are getting pushed aside this year.
Inside InstrumentationI will always remember the first time I peeled off a bit of onion epithelium and placed it under a microscope.
